Property: indexOf
	This method is provided only for browsers without native *indexOf* support.
	For more info see <http://developer.mozilla.org/en/docs/Core_JavaScript_1.5_Reference:Global_Objects:Array:indexOf>

	*indexOf* compares a search element to elements of the Array using strict equality (the same method used by the ===, or triple-equals, operator).

Arguments:
	item - any type of object; element to locate in the array
	from - integer; optional; the index of the array at which to begin the search (defaults to 0)

Example:
	>['apple','lemon','banana'].indexOf('lemon'); //returns 1

Returns:
